This paper proposes “path mapping”, a method of delay estimation for technology independent combinational circuits. Path mapping provides fast and accurate delay estimation using the common ideas with the tree covering based technology mapping. First, path mapping does technology mapping for all paths in the circuit with minimum delay. Then, it finds the most critical path among all the paths i...

Organizational critical activities (OCAs) are activities which must receive constant management attention in order for that organization to be successful in its industry. Some empirical studies have shown that all of these activities may not be well supported by organizations’ websites. This research attempts to develop the evaluation methodology which can be used to assess how well an organiza...

People traditionally have considered the number of counters in the critical path as the met ric for the performance of a multiplier This report presents the view that tree topologies which have the least number of levels do not always give the fastest possible multiplier when constrained to be part of a microprocessor It proposes two new topologies hybrid struc ture and higher order arrays whic...

In this paper, we study the performance of the continuous phase modulation (CPM)-based orthogonal frequency division multiplexing (CPM-OFDM) system. Also, we propose a CPM-based single-carrier frequency domain equalization (CPM-SC-FDE) structure for broadband wireless communication systems. The proposed structure combines the advantages of the low complexity of SC-FDE, in addition to exploiting...

Critical Path Profiling is a technique that provides guidance to help programmers try to improve the running time of their program. However, Critical Path Profiling provides only an upper bound estimate of the improvement possible in a parallel program execution. In this paper, we present a new metric, called Slack , to complement Critical Path and provide additional information to parallel pro...

A large project requires proper scheduling to obtain the duration of development and costs incurred more optimally. Optimization is submitting efficient solution by using various alternatives that can be reviewed in terms cost time. problems solved operating research. Selected Critical Path Method Genetic Algorithm as a compelling method for planning an methods rolling schedules because this co...

Project cannot be done without planning, scheduling and an estimation of its duration for completion. Every project that has to undertaken must have a deadline it completion but not every goes as schedule. Hence, applications scientific method such CPM, PERT are often very useful in management scheduling. This study was on the application CPM building construction taking case Mosul Estate const...

This paper addresses the joint path delay and time-varying complex gain estimation for continuous phase modulation (CPM), over a time-selective slowly varying Rayleigh flat fading channel. We propose two estimation methods: an expectation-maximization (EM) algorithm for path delay estimation in a Kalman framework, and a Maximum a Posteriori (MAP) method for joint path delay and complex gain est...

The paper investigates the effects of technology scaling on area/delay characteristics of registertransfer level (RTL) designs. Based on experimental modeling of RTL components and interconnect, whose feature sizes have been scaled down from 1.5 m to 0.25 m, we evaluate the critical path delay and area of several data-paths and report on efficiency of layout and RTL optimization techniques at t...
